No. He's just lazy. He has little free time in his hand where he wants to play games or VNs or watch animes instead of working on the forum on which he lost motivation to work on. This is what he really lacks, motivation, hence he's lazy. I have spoken to him on Skype, IRC, and had heard regarding him from people who actually met him IRL.
He's just like that. If there is something he wants to do; he'll do it in a day or so in a flash. But if it's something he isn't very interested in himself, such as a good suggestion; he'll take ages, ranging from a month to more or take indefinite period of time.
The bugs not being cleaned is a similar situation.
